Dear K.CoSy Charter members and friends of CoSy ,
If you have visited http://CoSy.com recently , you will have seen
that the period of charter subscriptions at a token cost , they having
filled their purpose , has passed . It has produced a strong
understanding of CoSy's powerful advantages over tradition styles of
interface among a nucleus of individuals who took advantage of the
charter availability .
During this year , I have also evolved the mechanisms and usages of
CoSy so that all my various responsibilities , the timestamped records
of the relationships , their transaction histories , and the necessary
tax filings , are current and reduced to a fraction of my time .
I have also embedded in CoSy ( and my own experience ) the life cycle
- the formation , accounting , and equitable dissolution - of a small
partnership . I should have been spending my time pruning and shorting
my portfolio , but trading seemed such a secondary activity compared
with the potential of direct creation .
Trading for your family's account , tho , is the ultimate
responsibility if your family's assets are in the form of securities .
The server-side support for such activities is , of course , the
domain K rules . ( see http://island.com for example . )
This activity is now sets the value of my time .
Now that the Charter period is over , CoSy will focus on several
markets .

Current Kx customers

Here the issue of an individual client-side license for the K
underlying CoSy is not an issue . If your corporation already
is a client of Kx Systems , we should talk .
CoSy , the K IDE
CoSy is the only Interactive Development Environment (IDE)
available for K . I must admit I am itching for opportunities
to benchmark its productivity against the scripting-compiling
environments commonly used for K programming .
CoSy is compatible with Kdb , and I seek tasks that expand
the synergy between the two .
Teaching K with CoSy
CoSy , being an interactive notebook , is incomparable for
teaching K in a simple step by step fashion where each line
can be replicated , dissected , reexecuted with immediate
results displayed , all saved with a keystroke .
Working literally from within the K-tree , the concepts and
subtilties of K's structure and notation become immensely
more tangible and therefore learnable . Thru presenting
CoSy and K to a wide variety of people , I have refined the
sequence of introduction of concepts to ease the path to
understanding of Arthur's remarkable creation .
If you are a client of Kx and have personnel , perhaps including
yourself , to whom knowledge of , or a deeper knowledge of K
would be valuable , we should talk .
Consulting in K with CoSy
Implicit in the above is that I am seeking consulting tasks in
K and Kdb to test the reality of my rhetoric . I look forward
to working with the Kdb and large systems experts whose knowledge
of these environments is so complementary to my own concentration
within K itself .
All of these uses bundle the necessary CoSy license .

Potential Kdb server customers

If you have leading-edge large scale quantitative database
serving applications where Kdb technology is uniquely capable ,
let us pull it all together for you with the added benefit
of CoSy as an interface for your most sophisticated users .

Independent Client-side KoSy

The highest value use for CoSy is clearly as the personal "noteComputer"
for quantitative individuals who run their own affairs , whether family
or business . This requires a substantial amount of personal tutoring
and customization embedded in a top of the line Sony notebook .
At this point in time , this can only be supplied with Kx's free
download license which , while pointing out a history of 5 years
availability , Kx reserves the right to revoke at any time .
We are continuing to work hard to resolve this difficulty , but in
the nonce , we will be working to demonstrate the value of the
CoSy interface to K within the Kdb server market .
Charter Subscribers
I do plan to continue to aperiodically upload updates to the basic
CoSy.csd which is on the CoSy Members page . As Charter subscribers ,
you will continue to have access until the end of October , or
anniversary of the date of your subscription , whichever is later .
If you not a customer of K but are finding CoSy of significant
value to you , and can accept the limitations of the current K
license , let me know .
In any case , let me know . Your perception of the client-side value
of the power of K , made comfy by CoSy , will build the case for an
appropriate licensing structure .
Thank you all for your early support .
You have played a role in the creation of
an ultimate built on an ultimate .
